Embodiment Construction
[0009] according to figure 1 As shown, the shift oil cylinder piston rod 8 is installed on the shift plate, and the sliding shaft 7 is installed on the shift plate, and the driving rod connector 6 is installed on the sliding shaft, and the driving rod 5 and the driving rod are connected on the connecting head. Shift fork 4, shift fork is connected with inner tooth cover 3, and high-grade gear 1 and low-grade gear 2 are respectively installed on both sides of inner tooth cover.
[0010] Working process of the present invention:
[0011] The piston rod of the hydraulic oil cylinder pushes the connecting head of the driving rod to drive the driving rod, the shift fork and the inner gear sleeve to move forward, so that the inner gear sleeve meshes with the low gear, and the screwing machine is replaced with a low gear.
[0012] The piston rod of the hydraulic cylinder pulls the connecting head of the driving rod to drive the driving rod, the shift fork and the inner gear sleeve t...

The invention provides a hydraulic gear-shifting device for a screwing machine. A piston rod of a gear-shifting cylinder is arranged on a gear-shifting plate; a sliding shaft is arranged on the gear-shifting plate; a shifting lever connecting head is arranged on the sliding shaft; a shifting lever and a shifting fork are connected to the shifting lever connecting head; the shifting fork is connected with an inner toothed sleeve; and a high-grade gear and a low-grade gear are respectively arranged on two sides of the inner toothed sleeve. The shifting lever connecting head is pushed and pulled to drive the shifting lever, the shifting fork and the inner toothed sleeve through the piston rod of the gear-shifting cylinder, so that the high-grade gear or the low-grade gear is engaged with a transmission mechanism gear of the screwing machine, and the high-grade operation or low-grade operation of the screwing machine is realized. High / low-speed gear shifting is realized, and the hydraulic gear-shifting device has the characteristics of flexible operation and is convenient to control and is suitable for serving as a gear-shifting device of a pipeline disassembly screwing machine.
Description
technical field [0001] The invention proposes a hydraulic shifting device for a twisting machine used in the field of machinery for disassembling and assembling a twisting machine for pipelines. Background technique [0002] Before the present invention proposes, when being used for connecting or removing by the pipeline of threaded connection, often use screwing machine. However, the current buckle twisting machines all use manual shifting. Before shifting into gear, the gear shift handle needs to be pushed manually. The twisting machine requires two people to operate, which affects production efficiency and increases production costs. Contents of the invention [0003] In order to realize the hydraulic shifting of the twisting machine, the present invention proposes a hydraulic shifting device for the twisting machine. The device slides on the sliding shaft through the piston rod of the gear shift cylinder to push and pull the lever connecting head, drives the lever and...
